Dirty Girl isn't. Sorry, but it's just faux grime, a thin layer of bad behaviour that wipes clean with a two-ply tissue to reveal the real movie beneath - all shiny sentimentality.
Dirty Girl broadcasts its intent to be edgy and subversive - poking fun throughout at small-town, conservative attitudes toward sex and morality - without ever achieving subversion.
A handsome production that nicely evokes the 1920s and a likeable cast headed by McConaughey can't compensate for a Western-gangster film that's too diffuse and lacks a discernibel POV to be dramatically engaging.
Ultimately, this is just a big, dumb, commercial suspenser - but it's one of the best for ages, reminding us that it is still possible to make a high quality piece of popcorn entertainment.
A sociopathic serial poisoner provides everyone with the nihilistic zero they need in this intelligent and disheartening dramatic thriller for Generation Blank.
